IMPROVEMENT IN GRAIN-BINDERS.

Specification forming part of Letters lPatent No. 178,993, dated J une 20, 1876; application filed April 24, 1876.

To all whom 'it may concern: f Be it known that I, JOHN E. BUXTON, o Owatonna, in the county of Steele and State of Minnesota, have invented certain new and useful Improvements in Grain Binders, of which the following is a specification:

Figure 1 represents, in perspective, my grainbinding machine. Fig. 2 represents a side elevation of the same. Fig. 3 represents a transverse section, showing the pinchers and the twisting-wheel. Fig. 4 represents, in perspective, the griping device that holds the binding-wire while being twisted. Fig. 5 represents, in perspective, the reel partly broken away to exhibit the take-up spring attached' side in a continuous stream.'

My invention relates, also, to certain comhina-tions of a reciprocating and revolving cutoff, to arrest at times the grain descending continuously, anda slatted platform to receive itv and'hold it in proper vposition tov be bound. It relates, also, to a wire-twisting mechanism, in connection with nippers and a griping device, by means of which the grain-bundles are securely bound after having been held and compressed by my improved mechanism.

In the drawings, A represents an inclined slide, upon which the grain is received in a continuous stream, after having been elevated over the driving-wheel of that class of harvesters in which elevated aprons or belts are used. In thisslide A a series of slots, a, are

project upward at stated times and arrest the grain in its descent. The teeth b are attached to a bar, B, having an intermittent rotating and also a sliding motion back and forth upon guides A', attached to the frameof theslide A. When the teeth b of the cut-oli' are out of' the way of the falling grain, the latter will descend upon a slatted platform, C, that is held in position to receive the grain by means of a counterpoised weight, c. The platform G is supported by springs c at each end,to relieve the bundle of grain from too great a pressure when the bent arms D come down upon the bundle to compress it, in conjunction with the spring-compressor D', that is carried back and forth b'y a reciprocating frame, E, sliding upon guide-rodsf, attached to the main frame F of this machine. This reciprocating frame E carries, in suitable bearings e, a rock-shaft, H, to one end of which the crescent wire-carrier H1 is attached. Upon this carrier is located a frame, g, that carries the reel and the pulleys lt, used as guides for the binding-wire while it is brought from the reel to the nippers.

The reciprocating frame Eis moved back and forth by means of two connecting-rods, t', united to 'two crank-arms, I, attached to the main driving-shaft J. The rock-shaft H and with it the crescent'wire-carrierH1 are made to perform a semi-revolution by the action ot' the curved rod h', attached to one end of the roclgsh'aft H, passing through a loop, f', pivoted to the main frame, the rod l1. being curved in such a manner as to give-to the wire carrier the desired motion to bring the wire around the bundle of grain to. the nippers andto the wheel that is to twist it, while the carrier is brought tothe bundle of grain by the crankarms I and connecting-rods i. When the ivire band has been placed around the grain, and the ends are twisted, the sheaf is discharged by depressing or partly rotating the slatted platform C, by means of a hook, c', upon the reciprocating frame E, engaging with a rod, C', attached to one end of the pivoted shaft of the slatted platform C, while the frame E accomplishes its backward movement, and then the rod C is released, and the counterpoiseweight c returns the platform C to its normal position.

cut, through which the teeth b of a rake can The ends of the wire that form the bands are twisted together by means of a star-shaped wheel, K,mounted upon ashaft, k. This shaft carries a pinion, laf, that meshes with a bevelgear wheel, L, attached to a shaft, l, parallel to the main driving-shaft J., The shaft l is rotated periodically, so that the twistingwheel K can operate upon the ends of the binding-wire at the proper moment by means of a pinion, l', that can be moved in and out Vof gear with the gear-wheel j, on the shaft J,

sheaf by a griping device formed of two jaws,

o and 01, the jaw 0 being stationary, while the jaw ol is pivoted to the frame o2, and is operated, at the right time, by the cam 0. The

pinchers p, that cut the wire and retain one` end of it fast between them, are located on the opposite side of the twisting-wheel K, and are operated by a series of levers, p1 p2, and link p4, through a cam, P, mounted upon the main shaft J.

To provide against both ends of the wire band entering the same depression in the starwheel K, I revolve it one-half of a revolution, (after one end has been engaged in one of the depressions,) by means of an arm, N, attached to the main shaft, striking against the periphery of an india-rubber pulley, M, attached to the shaft ofthe twisting-wheel K.

The revolving rake b is operated` by rods b2, pivoted to its shaft B and to the frame E,and it is revolved, while the sla-tted platform G is free to receive the grain, by means of bent arms b3, attached to its shaft B, striking against a stop, a3, attached to the frame of the machine, and it is held from turning backward by means of a ratchet-wheel, b1, with.

which the spring-pawl b4 engages.

To regulate the tension upon the binding-` wlre, and produce a take-up mechanism for` the slack wire, I have mounted the reel Q` loosely upon a shaft, g, passing throughbearings 1n the frame g. This shaft q is kept from rotating too freely 4by a check-spring, q', of indla-rubber or other suitable material, pressing against a washer, r, resting against the frame g, the required pressure being produced by a nut, r', mounted upon the screw-threaded end of the shaft q. Upon this shaft g is attached a drum, S, containing a flat coiled spring, s. One end of this spring is attached to the drum at s, while the other end is free, and is bent in the form of a loop to receive a pin, @attached to the reel. Thus, when the binding-wire is drawn upon, it first winds up` the spring s until it overcomes the tension of the spring' q', and the shaft q is permitted to` the springs acting upon the pin t, attached to the reel.

regulated by means of washers between its spring and the frame.

To bind grain with this machine, motion is transmitted from the harvester to the main driving-shaft J, the binding-wire having been passed from the reel Q over the guide-pulleys dle of grain, through an indentation of the l star-wheel or twister K, to the pinchers, passing it under a hook, p3, upon one of the jaws. Then the pinchers close upon the wire, which is then cut by the sharp edges formed on the fore part of the pinchers, which can also be called nippers7 Then the griping-jaws o ol close upon the two ends of the wire adjacent to the bundles of grain,and retain them while the twisting-wheel K revolves, and fasten the two ends of the wire by twisting them together. To bring the wire down between the gripingjaws, the wire-carrier H1 is provided with a forked arm, H2, that carries the wire in the `desired position to be retained by the gripingjaws. Adjacent to the cutting-edge of the nippers there is a vibrating finger, p5, operated by the lever p2, through the link p", to lift the end of the wire from the piuchers, so as to have it out of the way when the new wire `is brought to the pinchers. After the sheaf has been bound, the main shaft J continuing to revolve, -the reciprocatingframe E recedes from it, carrying with it the wire-carrier H,

and unwinding the wirefrom the reel, one end of the wire being retained by the pinchers p, so as to obtain a length necessary for a band. During this retrocession` of the frame E the hook e ,located upon said frame, engages with the rod C attached to the end of the platform C that supports the sheaf, and discharges the latter. The platform C is then retnrnedto its normal position by the balance-weight c. During these operations the teeth b of the cut-off have remained in a nearly-vertical position, so as to arrest the grain falling in a continuous stream upon the inclined platform or slide A, although having a sliding motion `back and forth upon the guide-rods A', but when the frame E and wire-carrier H1 have receded far l f l described operations are repeated. Ihe tension upon the compressor Dl can be4 having a wire-carrier, H1, the reciprocatingr and revolving cut-off operating intermittently, substantially as and for the purposes described.

2. The combination ofthe twister-pinion, the rubber pulley, and the arm or knocker on the rotating,` shaft for operating the pinion intermittently, substantially as set forth.

3. In combination with a griping device to hold the wire and nippers to cut it, the twisting-Wheel K, constructed with indentations and serrations to receive the wire and hold it while it is twisted, substantially as set forth.

4. The' twister-Wheel K, provided with in dentations and serrations, as described, and adapted to operate substantially as set forth.

5. In combination with a reciprocatingframe carrying` a hook, e', to engage vwith an arm, C', attached to a platform for receiving and supporting` the grain while it is bound, the pivoted and balanced platform G, operated substantially as described.

6. In combination with a reciprocatin gframe and a wire-carrier, operated substantially as v described, the nippers p, having hook p3 upon one jaw, to receive the binding-wire and hold it, substantially in the manner and for the purposes set forth.

7. Incombination with platform C, supported by springs c', the vibrating bent arms D and spring-compressor'D, operated by reciprocating frame E, substantially as and for the JOHN E. BUXTON.
